MUSIC-LEAF TURNER.

To all whom it may concern:

Be it known that I, LOUIs LYNN \VHITE, of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for turning the leaves'of sheet-music rapidly and perfectly.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front View of my improved musioleaf turner. Fig. 2is a cross-sectional elevation of the same on the line 00 00, Fig. 1. Fig. 3 is a sectional plan view of the drivingwheel and one of the wheels carrying the rods.

The musicraek Ais provided with an opening, B, from which a slot or notch, 13, extends upward, and in the top of the opening B across-piece, G, is secured, which projects from the front and back of the rack, and in said cross-piece a rod or shaft, D, is journaled, the other end of which isjournaled in the ledge A of the rack, and which shaft D extends centrally through the opening B.

In a recess, A", on the ledge A a wheel, E, having a milled edge is rigidly mounted on the shaft or rod D, and in the opening B a cogwheel, F, is mounted on the squared part of the shaft, to slide on said shaft and to turn with it.

In the front end of the cross-piece G and an arm, 0, projecting from the face of the rack below the crosspiece (l, a shaft, G, is journaled in front of the shaft D, and on said shaft G a series of pinions, H, are mounted loosely and independent of each other, and one pinion being above the other. Each pinion is provided at its bottom edge with an outwardly-projecting flange, H, and each pinion H and its flange H are provided with a recess, I, occupying about one-fourth of the circumference of the pinion. From each pinion an arm, J,

projects, and on the outer end of each arm a spring-clip, K, or other fastening device for SPECIFICATION forming part of Letters Patent No. 340,749, dated April 2'7, 1 886.

holding the sheets or leaves, is secured. The shaft D passes through an aperture in an arm, L, secured below the cog-wheel F on a rod, M, guided to slide vertically on the crosspiece 0 and on an arm, N, on the back of the rack, which rod M is provided with a part, M, projecting through the slot B from the front of the rack. A latch, O, is pivoted on the face of the rack above the notch or recess B, and against the bottom edge of said latch the part M of the rod M is pressed. A spiral spring, P, surrounds the shaft D between the arm 0 and the arm L, and thus presses the latter and the rod M upward. A rod, V, having the bends or arms V and V is mounted to turn on the face of the rack, and is used to raise the rods J, to facilitate swinging them back on the right-hand part of the rack.

The operation is as follows: The several sheets rest on the right-hand side of the rack A, and each sheet is held at its upper right-hand corner by a clip, K, the clip K on the uppermost rod, J, being on the uppermost sheet, W. The cogwheel F is engaged with the uppermost pinion, H, and cannot drop, although it is not held raised, as the teeth of the cog-wheel cannot pass the flange Hof the uppermostpinion, on which it rests. The rod J and clip K being to the right, the recess I faces the front. To turn the first leaf, the milled wheel E is turned, andthereby the shaft D is turned on its longitudinal axis, and the c0g-wheel F turns the uppermost pinion, H, and swings its rod J and the leaf held by the clip on the end of said rod to the left. By this half-revolution of the pinion the recess I is brought to the rear, and thus permits of the cog-wheel F sliding down and engaging with the next pinion, H, and when this has been turned the cog-wheel F slides down again, and so on. Vhen all the leaves have been turned, the latch O is swung to one side to permit the spring P to force up the arm L, which strikes the cog-wheel F and pushes it up above the pinions H, which can then be swung back to the right-hand side of the rack. Then the rod M is forced down and locked in the lowered position by engaging its part M with the latch O. The cog-wheel F slides down and engages the uppermost pinion, and then the sheets can be turned again in the manner described.

If desired, mechanism may be provided for turning the shaft D by means of a pedal or treadle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a musiorack, the combination, with a shaft, of a cog-Wheel sliding on and revolving with said shaft, a series of pinions mounted on an additional shaft, and each having a flange at its bottom and a recess in the toothed edge, a

rod on each pinion,and a paper-holding clip on the swinging end of each rod, substantially as herein shown and described.

2. In a music-rack, the combination, with a shaft, of the cog-wheel F, the shaft G, pinions H, the rods J, the clips K- on the ends of. the same, the spring P on the shaft D, and below the cog-wheel F, and of mechanism for keep ing the spring compressed, substantially as herein shown and described.

3. In a music-rack, the combination, with the shaft D, of the cog-wheel F, the shaft G, the pinions H, the arm L,s1iding on the shaft, the rod M, to which the arm L is secured, and of the spring P below the arm L, and a latch for locking the arm L in thelowered po- 25 sition, to keep the spring P compressed, substantially as herein shown and described.

4. In a music-rack, the combination, with the shaft D, of the cog-wheel F, the shaft G, the pinions H, the rods J, the clips K, the arm 30 L, the spring P, the rod M, having the bent part M, and of the latch- O, substantially as herein shown and described.

5. In a music-rack having the opening B and slot B, the shaft D, the cog-wheel F, the 5 pinions H, the rods J, the clips K, the spring P on the shaft D, the arm L, the rod M, to which the arm L is secured, and which rod has a bent top part, M, and of the latch O,
